The 25-year old Brazil-born Spanish striker will be a transfer target for clubs in Europe this summer with Chelsea the most heavily linked side.
Reports have suggested that the Blues are set to go after Costa this offseason in a bid to bring some fresh goalscoring nous to Stamford Bridge, and although he has revealed there has been some talk, the former Valladolid man insists he is only worried about Atleti' Spanish La Liga and Champions League plights.
"I feel good at Atletico, I am happy in Madrid," Costa told Sky Sports Italia.
"We will see what happens, there are offers but it is too early yet to talk. Now I am just thinking about the end of the season, I want to win the Champions League and La Liga."
Atletico are currently on top of the Spanish league table with three fixtures remaining and are also into their first-ever Champions League final where they will take on arch rivals Real Madrid in Lisbon on May 24.
